短文改错。

My uncle is the owner of a restaurant close to that I live. Though not very big, but the restaurant is popular in our area. It is always crowded with customers at meal times. Some people even had to wait outside. My uncle tells me that the key to his success is honest. Every day he makes sure that fresh vegetables or high quality oil are using for cooking. My uncle says that he never dreams becoming rich in the short period of time. Instead, he hopes that our business will grow steady.
